NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 255,780, dated April 4, 1882.

Application filed February 7, 1882. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL GISSINGER, of Pittsburg, in the county ofAllegheny and State of Pennslyvania, have invented a certain new and useful Improvement in Nut-Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in nut-locks; and it consists ot' a hinged spring holding-plate for looking the nuts on the bolts ofthe sh plate or bar, the pintie of said hinge being connected to two ot' said bolts, all of which will hereinafter more fully and at large appear.

To enable others skilled in the art with which my invention is most nearly connected to make and use the same, I will proceed to describe its construction and operation.

. In the accompanying drawings, which form part ot' my specification, Figure l is a vertical and transverse section of a rail for railways, fish-bar, and hinged spring holding-plate; Fig. 2 is a transverse section ot. a fish-bar, hinged spring holding-plate, and its pintle. Fig. Sis a i'ace View ofthe tishbar, hinged spring holding-plate, and its pintle. Fig. lis a face View ofa blank for forming the locking-p.late.`

Reference being had to the accompanying drawings, Arepresents the rail for railways; B, the fish-bar for coupling rails together; C, the bolt, and D the nut for attaching the sh-bar to the rails. To two of thc bolts C is attached a rod,E,in themannerindicatedinFigS-tbatis to say, bending each end ofthe rod around the bolts and slightly bending the rod outwardly from the sh-bar, as indicated in the accompanying drawings.

The blank in Fig. 4 is formed from sheetsteel or semi-steel or other sheet metal having elasticity, and is bent into the form indicated in Figs. l and 2, so as to form the locking-plate F and springG, With the knuckle H, for forming the hinge`,in combination with thepintle E.

I am aware that hinged plates have been used in connection with iishbars forlocking the nuts upon the bolts; but such hinged plates have been found objectionable, which is due to the fact that the jarring action ot' the cars upon the rails very frequently displaces said plates, and thus allowing the nuts on the bolts to bejarrcd ott'.

By constructing the locking-plate as hereinbefore described, and providing it with the hinge Gr, said plate will be held lirmly in its proper position between the nuts with snfticient force to prevent any displacement of it, and Ltet can be readily turned out, as indicated by the dotted lines in Fig. 2, when .necessary so to do, for the removalot' the nuts off ofthe bolts. The line of force of the spring G upon the knuckle His above the axis of the pintle, as indicated by the line I, and therefore it will require considerable force to turn the hinged locking-plate F out, as shown by said dotted lines, and it will be impossible forany jarring of the rails to displace said plate.

Having thus described my improvement, what I claim is- "Ilhe locking-plate F,having spring G, and hinged on the rod or pintle E, in combination with the sh-bar B, bolt or bolts G, and nut or nuts D, substantially as herein described, and l'or the purpose set forth.

SAMUEL GISSINGER.
